Forthright Welkin

#125da2
Notes

Forthright Welkin (#125DA2) is a true azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (209°, 80%, 35%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

Welkin
noun

The archaic English word for sky or cloud-vault — used in Old English religious literature, Shakespeare's Henry V ("the welkin's vicegerent and sole dominator"), and the Scottish ballad tradition. Welkin color refers to the sky in poetic register: a saturated, slightly cool deep blue with the optical brightness of clean atmosphere.
